BuddyPress.org

Does this work? I tried it just now and its not adding a friend to already existing members profiles. Does it only add to members who sign up after this is installed? Its not doing that for me either. I copied the PHP, added the line at the top that is needed, saved it and popped it in mu-plugins and the option shows up and it says its successful when I add the user ID, but nothing really happens on the front end.
